1. Factory price & High quality control

Cylindrical roller bearings are of high load capacity and can operate at high speeds because they use rollers as their rolling elements. They can therefore be used in applications involving heavy radial and impact loading.
The rollers are cylindrical in shape and crowned at the end in order to reduce the stress concentrations. They are also suitable for applications that require high speed because the rollers are guided by ribs which are either on the outer or inner ring. 

There are different types designated as N, NU, NJ, NUP, NF (for single-row bearings like the following drawing); NNU, and NN (for double-row bearings depending on the design or absence of side ribs).
